is. >> rose: welcome to the program. tonight, a conversation with dick cheney. >> you know, for seven and a half years we kept the country safe from any follow on attacks, mass casualty attacks of the type of 9/11. we had good reason to believe that we were, in fact, likely to be targeted again. we did everything we could think of within the law blessed by the lawyers over in the justice department to make certain that that didn't happen again. we're in a situation now, charlie, what i worry about now, what i worried about then, is that the next attack isn't going to be guys armed with airline tickets and box cutters, it will be with chemical weapons or maybe even a nuke or just a dirty nuke, a truck full of stuff that you set off and you can spread radioactive material around the landscape. those are the kinds of attacks we have to guard against. it's not going te ju 300 people killed in one day. >> rose: cheney for the hour, next.
